It's April Fools Day already and I haven't gotten near as much done for MarchIntosh project as I'd hoped. COVID and a bad reaction to second shingles shot afterward took care of that. But the PowerBook100/RPi-CM4-Lite is coming along with the arrival of a benchtop power supply for the LCD today...

Can't imagine there'd not be a performance hit, but how bad might it be? Duo2300c would actually be the target machine. Pretty much same machine as 5300/1400, but with SCSI HDD option (supports SCSI HDD/Cable in upgrade package config) but no PCMCIA availability. So curious . . . for a...

Non-Flammable components beginning to arrive! :p 1920x1200 will be a workable resolution running under Ubuntu in a 10.1" diagonal. Much better than most laptops with 1920x1080 and far better than lower resolutions of many. Love the modern look of the larger LCD. No mounting tabs, but that...

I'll dig up the info, hopefully still on eBay purchase list. Centrifugal blowers are far more efficient at moving air than bladed fans and throwing the flow at right angles is perfect for this. Outlet's pointed straight at G3 card heat sink and HPV card which conflicts with 3.5" HDD installation...

I wish I'd your post over here first, I'd love to have a rework of this section as a Square -> Round duct converter for better airflow, with the blower mount at about the level of the ribs with a carrier for 2.5" HDD or BlueSCSI overtop the blower. Make for an nice bloweroni-SCSI-sandwich, that.

The every other frame notion is a worst case, last resort kinda deal. Spitballing every nasty approach I can possibly come up with here. ;) Vampire Video in the IIsi is a well and truly diabolical affair: - was wondering about bit-banging the DRAM frame buffer to do an end run around RBV...

Looks like we might keep it digital on a IIsi board reload for SE/30? The video signals are generated by the Apple custom RAM-Based Video (RBV) chip and are driven through a combination color lookup table (CLUT) and video digital to analog converter (VDAC) chip. Each monitor identifies itself...

Old project, wondering where it has gone. Full feature set here. Features CRT and LCD display support 24bit Standard VGA interface Separate VSYNC/HSYNC and combined CSYNC synchronization signals Composite BLANK signal TripleDisplay support 12bit Interface Compatible with DVI transmitters and...

:ROFLMAO: No power jack, no problem . . . TwinSlot fitment prototype of paper and cardboard laminated with flammable adhesives sitting in the PCI slot of an Alchemy/Gazelle machine that might be fired up however . . . :eek:

Caffeine is finally kicking in. :confused: Time shift can only be achieved by dropping every other frame? Would this induce unacceptable flicker? Wouldn't work on an LCD, but such wouldn't be required as it's digital to digital, no DACRAM timewarp required. However, phosphor latency of CRT...

Don't wanna tangentially muck up the fabulous IIsi into SE/30 thread that @zigzagjoe has running over at the MLA with this craziness. @Bolle posted parameters of the conversion problem. _______________________________________________________________________________ The Apple 12" 512x384 video...

@wottle what no eyebrows? :p

. . . one piece at a time! :p /JohnnyCash Tucked everything away and started looking for missing bits of a PowerBook 165c. I'm trying to get it back together to finally test after I snagged it for the MacAntFarm™ project two decades ago. I'd already acquired a couple of victims for that...

Looks like PowerBook 100 batteries are only 6V, so I guess the new build batteries from @360alaska are out of the picture. :confused: Unless someone chimes in with a better idea, I'll just go ahead with current limiting resistors on a thin PicoPSU I found today for the time being. Still...
